“…It was theorized that the yield of saffron decreases in terms of economic efficiency after the sixth year, but it is economically viable before the ninth to 10th year. The reason for the decrease in yield from the fourth to the fifth year (Koocheki & Seyyedi, 2020) or the sixth year (our finding) is that with the formation of high corm in the soil, soil firmness and compaction increase and soil fertility decreases (Koocheki & Seyyedi, 2020). During the growing years, due to the presence of saffron corms in the soil, it is not possible to order enough soil to improve soil conditions.…”

“…We estimated the highest yield is obtained in the sixth year, however, Koocheki and Seyyedi (2020) believe that the saffron SY increases with increasing field age until the fourth to fifth year, and then decreases. It was theorized that the yield of saffron decreases in terms of economic efficiency after the sixth year, but it is economically viable before the ninth to 10th year.…”

“…Each mother corm produces about five daughter corms per year if nutrition is well. Daughter corms are formed on the mother corms after flowering, and as a result, the density of the plant increases in each growing season compared to the previous year (Koocheki & Seyyedi, 2020). In a study, the number of corms in 1-to 8-year-old Note: Means in each column were separated using standard error (±SE).…”

The economic yield of saffron (Crocus sativus L.) has a wide range in different parts of the world, and it is not clear why this considerable difference exists. In this research saffron yield and yield components of 13 fields with varied geographic and climatic conditions were studied to determine which factor(s) are more important. Among the studied factors, temperature, field age, soil texture, bulk density, soil and water pH, irrigation events, and growth period had the greatest effect on saffron yield. The highest dry stigma weight, as economic yield, was obtained in three regions of Birjand (27 kg ha−1), Sarayan (24 kg ha−1), and Golshan (23.5 kg ha−1), followed by Neyshabur (18 kg ha−1) and Kashmar (17.5 kg ha−1), which had lower temperatures, coarse soil, balanced soil, and water pH, and longer growth periods. The average yields were increased until the sixth or seventh year (20.8 kg ha−1) and then decreased, however, it seems to be economic before the 10th year. Lower temperatures in early fall were important to stimulate flowering and increase yield in that year, and warm and sunny days in the spring are important for next year yields. We found that the optimal temperature for the first irrigation is ∼16°C and for flowering is ∼5°C–10°C. High‐yield fields did not have higher irrigation water volumes but more irrigation events (6.3), resulting in less water volume per irrigation. No direct relationship was observed between manure consumption and yield; however, processed manure increases yield by improving the soil structure and moisture retention ability. Fields with a complete chemical fertilizer composition had higher yields. It was concluded higher yields are achieved in saffron fields where regions are higher in altitude (at least 1300 m) and lower temperature in early autumn with complete fertilizer composition (especially sulfur and iron). There was no evidence of high salinity sensitivity of saffron.

“…Some literatures on bawang dayak refer more to the content of secondary metabolites and their pharmacological activities. Koocheki & Seyyedi (2020) recorded that N, P, K content of saffron corm as 1.41%, 0.28%, and 0.92%, respectively, on a dry weight basis. The N and P might be remobilized and stored in the corm at the same time with leaves senescence.…”

“…By shortening the corm dormancy period, flowers appear before getting cold, and it helps to avoid frost damage [12]. e goal of this study was to investigate the effect of pre-cold treatment and different levels of SA on saffron flowering time and changes in total soluble sugar, starch content, and enzymatic activities in saffron corm.…”

Saffron is an important flowering plant, generally known as a golden condiment. The present study was performed to find the influence of different levels of SA and pre-cold treatment in the dormancy period of saffron and their effects on content enzyme activity. The results indicated that the SA2%, SA1%, and, pre-cold treatments took the shortest day to flowering. PAL enzyme activity was highest in pre-cold treatment. The higher total amount of protein was measured in the control, SA1% and SA2%. The highest amount of starch content and total soluble sugar was detected in pre-cold, SA2%, and control, respectively. No significant differences between treatments were present for CAT, PPO, GPX, and APX enzymes activity. There was a negative significant correlation between flowering time and some studied traits, i.e., starch and PAL activity. Applying SA and pre-cold treatment can induce saffron flowering and effect on pal enzyme activity and corm total protein, sugar, and starch content accordingly.
